Ron Gray Posted June 7, 2022 Author Share Posted June 7, 2022 Flying surfaces are film, fuse is composite. 1 Quote Link to comment Share on other sites More sharing options...
Jon H Posted June 7, 2022 Share Posted June 7, 2022 I am with paul on the firewall situation. All 3 of mine have been utterly hopeless with my P39 having 1/4 inch gaps between the wood and the glass. Not good ? I first noticed it on my la7 when i propped up the finished model on its nose for a photo. 20 seconds later there was a tearing sound and the model slumped a little. Inspection showed the plate had completely let go Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted June 7, 2022 Share Posted June 7, 2022 Mine was cut out, with a rough bit of ply badly glued, so was it it's first owner that cut it out ?. Quote Link to comment Share on other sites More sharing options...
Jon H Posted June 7, 2022 Share Posted June 7, 2022 I was going to PM you Ron but i might as well leave this here. I fired up the Hurricane's 200i just now in preparation for sending it. I wanted to try the new dumpy exhausts from the FT series engines on it and try it with a fuel line T piece and the new Optiful laser 5 pro. So, i fired it up using a small ish 17x8 apc prop and after a short time to warm up gave it the big one. And what a big one it was. Peak of 9100rpm which was way above my expectation of 8500-8600. Once hot the rpm fell away to about 8900 and held there which is perfectly fine. Performance was excellent with the T in the fuel line and once adjusted for the new fuel i saw an idle as low as 1000rpm, although 1500 is a more realistic low for reliability and 1800 recommended as a flight idle. The small exhausts were no bother either and the thing sounded awesome. I will get it packed up and out the door asap. 2 Quote Link to comment Share on other sites More sharing options...

Well, it ran so nicely i almost tucked it under my arm and went home. Lucky for you it was too hot to handle at the time ? As for everyone else, i have the components for another 14 of them prepped and ready so i hope i can start dishing them out soon. I just need a few more parts, and to clear some other jobs. I will likely build them in pairs to preserve my sanity as much as possible. 1 Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted August 13, 2022 Author Share Posted August 13, 2022 (edited) The 17th September (OW Scale weekend) is rapidly approaching and the Hurri has been sitting on the workbench with no work having been done on it since I rubbed the fuse down. So, despite the heat, I decided to make a start on the fitting of the new bulkhead to take the Laser 200i. As with the ESM Mustang (Laser 160i) the front of the fuse needed to be removed and the new bulkhead located about 80mm further back. Now this presented an issue, unlike the Mustang the Hurricane has quite a sharp taper on the nose which meant that if I just cut off the existing bulkhead I couldn't then just slot the new one in further back as it has to be larger than the hole left by the old one (the taper on the fuse). Plus I wanted to keep as much of the exiting nose in front of the new bulkhead in place to allow for the glassing overlap to give it strength as you can't easily get behind it to glass from the back. With me so far?? So this is what I've done. Existing bulkhead cut off with panel saw I then cut back the top half of the fuse so that the new bulkhead can slide down from the top The new bulkhead (12mm ply) will sit in front of the one you can see in the last photo by 13mm so to give more strength to the top half where I've cut the fuse back I cut a backing former Which was then epoxied to the fuse and to the existing former (fuse is inverted in the next shot) I will be gluing in some backing blocks for the bottom half of the new bulkhead to make it easier to position it in the correct position, that will be tomorrow's job.

Ron Gray Posted August 21, 2022 Author Share Posted August 21, 2022 Well the Covid infection is gradually leaving me after nearly a week so I was able to spend 10 minutes here and there (resting in between!!) and have made some progress. The new engine bulkhead was epoxied in place using the threaded rod method to locate it correctly in relation to the spinner ring. Once that had set I was then able to glass the front lower half from the front and the top upper half from the back. The large holes on the right are to allow the hot air to exit from the engine compartment. 2 Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted August 23, 2022 Author Share Posted August 23, 2022 Still can't spend too long working on things as COVID tiredness kicks in, but I'm getting more time as each day passes the annoying thing is that Sara now has it and is confined to bed and I'm a useless nurse! Anyway, some progress. Tank recess cut in top of wing and opening lined and glassed Tank support bracket 3D printed Engine does look nice in the nose But it looks like I will have to convert it to the tropical one to hide the front pot (balsa on the exhaust port is where I cut off the previously fitted (hideous) ones, which will be replaced with 3D printed ones) 2 Quote Link to comment Share on other sites More sharing options...
Peter Jenkins Posted August 23, 2022 Share Posted August 23, 2022 Just do the flypasts with the nearer wing low and that will hide the front pot! Rest of the time, it will be impossible to see! Looking good! Sorry to hear that Covid is having such an impact on both of you. Get well soon both! Quote Link to comment Share on other sites More sharing options...

Ron Gray Posted September 2, 2022 Author Share Posted September 2, 2022 Time to tackle the cowl! The previous owner has cut quite a large hole on the underside as he needed clearance for the gas engine he had installed so this needed filling prior to cutting out for the front pot of the 200i. I have been in correspondence with a US company who have some cowls in stock but thought that I’d do some work on my one whilst waiting for a price for the US one. Having searched through my workshop I couldn’t find any pieces of plastic that could be used as a temporary former to support the glassing so I used strips of old 1/32 sheet balsa instead. The inside was then glassed Leaving this on the outside which will be sanded down 2 Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted September 2, 2022 Author Share Posted September 2, 2022 And 10 minutes later sanded ready for a bit of filling 2 Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted September 2, 2022 Share Posted September 2, 2022 Funny way to cover the hole, why didn't you either tape over the balsa so that it didn't stick to the fibre glass or use a sheet of thin plastic a as a mould ?. still you are getting there.

Ron Gray Posted September 2, 2022 Author Share Posted September 2, 2022 Cutting the tape to the shape of the hole would be a pain. Re-read my post re plastic! Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted September 4, 2022 Author Share Posted September 4, 2022 (edited) I thought that I’d better make a start on the canopy. A couple of months ago I ordered one for an 88” Hurricane from Sarik which, after much chopping, fits quite well. So I added some aluminium tape for the canopy frame Then formed the screw heads and masked it all up in readiness for paint. TBH I haven’t spent a lot of time on this as it’s going to be redone at a later date because I want to cut the canopy and make it sliding. But it will do for now.
